BUFFER-BEAM.

To all wiz-0m t may concern Be it known that I, CHARLES T. VVEST'- LAKE, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Butler-Beams, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a top plan view of my buiiler' beam. Fig. 2 is a front elevational view of the same. Fig. 3 is an end view. Fig. l is a detail view of the removable end block.

This invention relates to an improvement in butler beams for railway locomotives, the object being to construct a butler beam with recesses at one of its ends to accommodate the movement of the piston rod extension. These recesses are preferably closed at their outer end by means of a filler block, said filler block being held in position by bolts which pass therethrough.

In the drawings: l indicates the top wall which is preferably provided with openings throughout its length for the passage of the chaplets, or anchors, which hold the core in position.

2 is the rear wall, 3 the front wall and 4 the bottom wall, which latter is also preferably provided with openings for the passage of the chaplets.

The ends of the beam are provided with laterally opening recesses 5, the top and bottom walls of which are provided with longitudinally disposed ribs 6. 7 is the liller block having grooves 8 in its top and bottom walls to receive the ribs 6. The inner end of the filler block is provided with cutaway portions to provide a space for the travel ot' the piston rod extension. The outer end or" the filler block is provided with pole pockets 9. 10 is a bolt for fastening the filler block in position.
